[MRI of the female pelvis: useful information for daily practice]

The MR findings of non-neoplastic gynecologic diseases were comprehensively reviewed. Pelvic inflammatory disease is a common benign disease affecting reproductive women, in which imaging findings are similar to those of malignant tumors of the adnexa. Torsion or rupture of benign ovarian masses can also mimic malignant ovarian tumors. Diagnostic keys to these conditions are presented in this review. The usefulness of dynamic contrast MRI in diagnosing ectopic pregnancy is also indicated. Placenta accreta is a catastrophic condition that occurs from labor to the postpartum period. Preliminary results of the diagnostic significance of dynamic contrast MRI in differentiating retained placenta accreta and normally attached placenta are also presented. Eclampsia is defined as convulsion complicated with pregnancy and is demonstrated as posterior reversible encephalopathy syndrome on imaging. Some commentary on eclampsia is given together with characteristic MR imaging findings.
